[Pharo-project] Sockets, events, semaphores, etc.

Hello all, Am I falling into a bad area of the image, or does Pharo poll for socket connections? As an example, look at ConnectionQueue>>getConnectionOrNil. Even the Socket waiting methods are all time-bombed. I would expect these methods to wait on a semaphore signalled by the vm on a socket event. It is one thing to offer time-bombed options, but I see nothing event driven at present :( Am I missing something? Bill
